  Just wondering about the frequency Response ( Hz ) Min Terminating Impedance ( ohm).
  
  Lets say some headphones has 102 ohm and another has 112 ohm..which one better ah? The bigger the better?
  
  And some frequency is 18 - 21,000 Hz while some is 14-24,000 Hz. The bigger range is better one?
  
  Anyone can enlighten me?

  Good question, I also always wonder about this. Human ear can only hear frequencies of 20Hz to 20KHz. Then whats the purpose of headphones advertising below 20Hz and above 20Khz?
  Do they mean that some humans have ultra powerful hearing senses?
  
  And what "household" items can produce noises at this frequencies? Very hard to find out.. But if any of you come across this kinda info please share..

  That frequency thingie helps you gauge how sweet the tweeter will be and how heavy the bass will pound your damn eardrums.
